Hello,
I have the following problem:
Take the simple example
FindRoot[Sin[x] +2, {x, 1.656 10^8, 1.653 10^8, 1.658 10^8},
EvaluationMonitor :> AppendTo[xs, x]]
In the Help we can read: "FindRoot[lhs==rhs, {x, a, a_min, a_max}]
searches for a solution, stopping the search if x ever gets outside the
range a_min to a_max. "
But when I display xs I can see, that there are also two complex
numbers used.
This is a problem if I use a function (in my case a compiled one)
inside FindRoot, which only accepts real numbers.
So how can I suppress the using of complex numbers in FindRoot?
Best regards,
Paul
